What we are seeing today is a late June version of April like showers and/or a thunderstorm. There's very cold air up in the sky and warm air near the ground. This creates instability in the atmosphere and there's just enough moisture to generate a spot shower or thunderstorm, especially during the afternoon and early evening.
But for the most part, it is not raining and humidity is low with mostly sunny skies near the shore and partly sunny skies inland. Temperatures today warm to about 85 degrees in southern New England, 70s to near 80 degrees further north. Wind for the most part from the southwest at 10 to 15 mph.
Any afternoon showers will evaporate quickly with the setting sun, temperatures tonight will be comfortable, low in the 50s and 60s.
The Monday forecast is pretty much the same although temperatures are not quite as warm. We are in the 70s to near 80 degrees with sunshine and passing clouds along with the threat for a shower or thunderstorm. Any showers and storms are brief but can be intense.
For the middle of the week will be watching an attempt for warm and humid air coming back northward. But at the same time cool air from Canada will be pressing south, that increases the possibility of more organized showers and thunderstorms on Thursday and Friday as the temperature and humidity come up a bit.
Early next weekend is for more of the same, temperatures creeping up a bit, but perhaps more humidity and a better chance for showers and thunderstorms each afternoon. It's still a long way off but Fourth of July does not look too different.
